More Information
Summary:During an information-extraction technique, a user of an electronic device may be instructed by an application executed by the electronic device (such as a software application) to acquire images, with different orientations (which are known to the user), of a target location on a document using an imaging sensor, which is integrated into the electronic device. After the user has taken a first image and before the user takes a second image in a different orientation of the electronic device (and, thus, the imaging sensor), the electronic device captures multiple images of the document. Then, the electronic device stores the images with associated timestamps. Moreover, after the user has taken the second image, the electronic device analyzes one or more of the first image, the second image and at least a subset of the images to extract information proximate to the target location on the document.
